2-Aminoadipate Transaminase: A PYRIDOXAL PHOSPHATE containing enzyme that catalyzes the transfer of amino group of L-2-aminoadipate onto 2-oxoglutarate to generate 2-oxoadipate and L-GLUTAMATE.L-Aminoadipate-Semialdehyde Dehydrogenase: An enzyme that catalyzes the oxidation of L-2-aminoadipate 6-semialdehyde to L-2-aminoadipate (alpha-aminoadipic acid). It is involved in the biosynthetic pathway of LYSINE.2-Aminoadipic Acid: A metabolite in the principal biochemical pathway of lysine. It antagonizes neuroexcitatory activity modulated by the glutamate receptor, N-METHYL-D-ASPARTATE; (NMDA).Alanine Transaminase: An enzyme that catalyzes the conversion of L-alanine and 2-oxoglutarate to pyruvate and L-glutamate. (From Enzyme Nomenclature, 1992) EC 18.104.22.168.4-Aminobutyrate Transaminase: An enzyme that converts brain gamma-aminobutyric acid (GAMMA-AMINOBUTYRIC ACID) into succinate semialdehyde, which can be converted to succinic acid and enter the citric acid cycle. It also acts on beta-alanine. EC 22.214.171.124.Transaminases: A subclass of enzymes of the transferase class that catalyze the transfer of an amino group from a donor (generally an amino acid) to an acceptor (generally a 2-keto acid). Most of these enzymes are pyridoxyl phosphate proteins. (Dorland, 28th ed) EC 2.6.1.Aspartate Aminotransferases: Enzymes of the transferase class that catalyze the conversion of L-aspartate and 2-ketoglutarate to oxaloacetate and L-glutamate. EC 126.96.36.199.
